Hi, I would appreciate if you could help me out. I have a Schecter PT special, and It has a single and a p90, as well as a push pull to turn the whole thing into parallel.
Could It be possible to put a toggle to do the in phase / out of phase thing? (It would be sick if the toggle could be connected somehow to the push pull that does the series parallel thing, as then I could have the 3 stock tones plus series in phase, series out of phase and parallel out of phase)
What you want is easily done. You can wire the phase switch on either pickup, but as per your diagram, the neck P90 has a braided shield, so it will be easier to do this with the phase switch on the bridge single coil. The phase switch will be "first in line" after the pickup and before the series/parallel switch. To do so:
First disconnect the bridge pickup wires, both "hot" and ground.
Next, you will need a DPDT switch, either another push/pull or a separate toggle switch. If you want to use a second push/pull, you would swap it in place of the second potYou will wire the two leads from the single coil to the phase switch as shown by this diagram:
